EFFECT OF PHYSICAL ACTIVITY ON VARIABLES OF LUNG FUNCTION: AN OBSERVATIONAL STUDY
Journal Title: International Journal of Basic and Applied Physiology - Year 2014, Vol 3, Issue 1
Abstract
Background and Objectives: Physical activity is known to improve physical fitness and to reduce mortality and morbidity from numerous clinical conditions .There is positive relation seen between physical activity and variables of lung function (FVC, FEV1,F EV1/FVC, FEV0.5, PEFR, FEF 25-75%, MVV).The major purpose of this analytic type of observational study is to explore the role of physical activity on respiratory fitness in healthy people. Methods: 90 subjects of age group 18-25 years divided into three groups. Each group is having 30 subjects. Subjects were divided into three groups according to leisure time physical activity assessed by metabolic equivalent minutes/week. Variables of lung function recorded were FEV1, EV1/FVC, PEFR, F EF25-75, and MVV. Results The results of present study were analysed, each group was compared by using ANOVA. p value <0.05 were considered significant. In the present study values of FVC, FEV1, FEV1/FVC were increased .FVC, FEV1, FEV1/FVC increased significantly with increase in physical activity (p<0.05) whereas FEF 25-75% and MVV showed highly significantly increase (p<0.001). Interpretation & conclusion: Present study strongly suggests that the intensity or severity of the sports determines the extent of strengthening of the respiratory muscles with a resultant increase in the lung volumes
